Four Winns debuts TH33 and TH38 power catamarans
by Four Winns 24 Jul 13:53 PDT
Engineered to transform boating experiences into refined escapes, the new Four Winns TH33 and TH38 set a new standard for power catamarans of its size as the latest addition to its TH (Twin Hull) Series, launched in 2023.
New TH33: Redefining horizons without compromise
The TH33 blends Four Winns' 50 years of premium American craftsmanship and iconic design with bold innovation. Building on the success of the first launch in the series, the TH33 is an instinctive power catamaran meticulously designed for those who demand more space, more stability, and more memorable days on the water.
"The TH33 is a unique concept that simply brings more to boaters," says Four Winns Product Manager Alexis Chas. "The TH33 is more than a new addition to the TH line—it's a bold new step in redefining the experience of boaters."
More space, stability and efficiency
The TH33's power catamaran design impressively offers boaters the space of a 40' (12.92m) monohull. Using the entire 12'6" (3.81m) beam of the 33-footer, over 400 square feet of versatile living space is available for relaxing, entertaining, and enjoying sun-filled days cruising on the lake or through coastal waters.
The width between the twin hulls brings enhanced stability. Its wide stature distributes weight evenly across a broader footprint than monohulls, significantly reducing roll motion. This enhanced stability transforms every moment onboard into a more enjoyable, safer, and more effortless experience for everyone aboard.
Increased stability also maximizes efficiency. While boasting the living space and comfort experienced on a larger size monohull dayboat, the TH33 navigates smoothly through the water with less drag. Reduced drag decreases the amount of power and fuel required to obtain a comfortable speed, giving the boat a significant advantage over monohulls and offering a brand new and desirable life on the water for Four Winns boaters.
Clever design results in refined comfort
The meticulous and clever design of the Th33 offers guests a refined and elevated onboard experience. Whether enjoying brunch onboard with friends or relaxing at the sandbar solo, every detail of the boat is crafted to maximize the comfort of your adventures.
Comfort begins with space and attention to detail. Expansive deck areas make the TH33 ideal for large group gatherings, sunbathing, and fully enjoying days on the water. At the helm, dual extra wide forward-facing seats, complete with dual 12" Garmin displays and a 7" passenger display, bring guests and the captain closer together. They can enjoy spectacular views and a smooth ride while being secure and protected behind a full-beam protective windshield with the signature Four Winns cross curve design. An optional hardtop enclosure brings year-round safety and enjoyment regardless of the season.
At the stern, a spacious transom ladder placed between the Mercury outboards provides safe and instant access to the water.
Traveling to any area on the boat is also safer and more enjoyable. A wide and easy access to the head and center walkthrough enhance safety, while natural wood flooring or color matched Marine Mat pair with the premium upholstery for a seamless and cohesive interior design. Guests won't have to travel far to find the convenient galley, centered in the living space. The galley is well furnished with a sink, trash compartment, refrigerator, and optional electric grill, bringing the boat's helpful amenities closer to guests.
Sophistication in every stitch
Four Winns' commitment to superior craftsmanship is on full display in the TH33. From choosing your choice of hand-stitched cognac-colored leather seating or light grey interior, to marine-grade upholstery, every surface elevates your experience.
"The craftsmanship is unmistakable—from the signature curved windshield to the upscale textures and finishes," says Alexis Chas. "It's where modern design meets the Four Winns legacy."
The ultimate dayboat
Below deck, the TH33 continues its large offering of space with a sizable storage compartment. An optional Cabin Package transforms this area into a cozy mid-day retreat.
A dayboat for today and tomorrow's boater
The TH33 is the epitome of refinement without compromise. Its design supports a secure and social experience with all the functional space of a bigger boat. Available options for boaters to customize and adjust their dream dayboat are endless, from push-button controls to flexible seating arrangements.
Whether cruising the coast of the South of France or anchoring in the Florida Keys, the TH33 lets you expand your horizons and make the most of every moment.

New TH38: Redefining what a dayboat can be
The TH38 is enhancing onboard protection, expanding living space, and pushing the boundaries of functional ingenuity and comfort—while maintaining the stability, accessibility, and performance the TH Series is built upon.
Eliminating limitations, extending safety
The TH38 masterfully blends the adventurous spirit of a dayboat with the refinement and livability of a cruiser. Designed in collaboration with Garroni Design and naval architect Marc Lombard, the TH38 introduces two helm windshield versions: a full-height windscreen for maximum protection and seasonal comfort, or a low-profile version that enhances airflow and open-air freedom.
"The TH38 removes boundaries for boaters, including where and when they can enjoy the finer side of life aboard a Four Winns boat," states Four Winns Product Manager Alexis Chas. "The twin hull structure delivers a smooth ride and superior stability whether cruising on inland waters or exploring coastal waters in the South of France, and our new features offer new opportunities."
Four Winns boaters can comfortably enjoy year-round boating with the TH38's full-height windscreen and new sport-top options. "The high windshield and enclosure enhance comfort and safety while extending the boating season," says Alexis Chas. The low windshield option maintains the spirit of an open boat while including optional protection on the sides of the cockpit.
With its modular cockpit seating layout, the versatility of the boat's deck allows occupants to craft their experience while safely traveling through the center of the boat. From an open social space to a unified dining area, the TH38's deck instantly transforms to meet the wants and needs of the moment.
Versatile outdoor living
Up to 14 guests can enjoy the TH38's impressive 14'8" beam and over 500 square feet of deck space, which delivers ample room to relax, entertain, and explore in style. The joystick piloting system, twin digital displays, and advanced dash design offer intuitive control, making maneuvering a breeze even in tight spaces, and the handstitched forward-facing cockpit seating provide the captain and passenger plenty of room to operate and socialize.
A wide transom swim ladder integrated between the twin outboards ensures effortless access to the water, whether you're diving into ocean waves or enjoying a serene freshwater retreat.
Comfort beneath the surface
Below deck, the TH38 offers two identical, spacious, air-conditioned cabins, each with a large berth, ample storage, privacy blinds, and ensuite heads featuring large enclosed glass showers. Oversized hull windows flood the rooms with natural light, creating a calm, private escape for overnight stays or longer cruises.
"The TH38 is a refined response to what today's boaters are asking for: more space, greater stability, and the freedom to shape their adventures," says Alexis Chas. "It's a boat designed to unlock new experiences and deliver the finer side of life on the water."
The TH38 delivers the comfort of a cruiser, a spacious open layout, and the utility of a family catamaran—all without compromise. Buyers can tailor their TH38 with a wide range of interior and exterior color palettes, electronics packages, and accessories.
